Accuracy Of Irrigation Efficiency Estimates, A. J. Clemmens, Charles M. Burt
Accuracy Of Irrigation Efficiency Estimates, A. J. Clemmens, Charles M. Burt
BioResource and Agricultural Engineering
Evaluation of actual irrigation system performance should rely on an accurate hydrologic water balance over the area considered. In a companion paper, water uses are categorized as consumptive or nonconsumptive, and beneficial or nonbeneficial. Real performance is based on water uses over a specified period of time, rather than observation of a single irrigation event (with associate potential, but not yet actual, consumptive and/or beneficial uses). Once the components in the water balance have been determined, it is shown that the accuracy of irrigation performance parameters can be determined from the accuracy of the components in the water balance, using …

It is essential to standardize the definitions and approaches to quantifying various irrigation performance measures. The ASCE Task Committee on Defining Irrigation Efficiency and Uniformity provides a comprehensive examination of various performance indices such as irrigation efficiency, application efficiency, irrigation sagacity, distribution uniformity, and others. Consistency is provided among different irrigation methods and different scales. Clarification of common points of confusion is provided, and methods are proposed whereby the accuracy of numerical values of the performance indicators can be assessed. This issue has two companion papers that provide more detailed information on statistical distribution uniformity and the accuracy of irrigation …

BioResource and Agricultural Engineering
When deciding what chemicals to inject, there are numerous considerations to be made. This paper addresses some of the more common factors which should be considered, but which are often overlooked. Because nitrogen fertilizer is injected more widely than any other nutrient, special attention is given to it
